CROSS-REFERENCE TO RELATED APPLICATION(S)

This patent application is a continuation of, and claims a benefit of priority under 35 U.S.C. §120 from U.S. patent application Ser. No. 13/461,351, filed May 1, 2012, entitled “SYSTEM AND METHOD FOR SENDING, DELIVERY AND RECEIVING OF FAXES,” which is hereby fully incorporated by reference herein for all purposes.

TECHNICAL FIELD

This disclosure relates generally to digital content delivery in a network environment. More particularly, this disclosure relates the transmission, delivery or reception of faxes through network based protocols or telephone networks. Even more specifically, this disclosure relates to the transmission, delivery or reception of faxes using distributed services.

BACKGROUND

A facsimile (fax) comprises a document in a digital image format. The document is associated with metadata that specifies a destination with respect to the publicly switched telephone network (PSTN). Thus, typically for at least a portion of the transmission, the document is transmitted over the PSTN. Faxing provides a secure, traceable and non-repudiable mechanism for content delivery and can be particularly useful in business environments.

Faxing, however, has limitations. For example, conventional fax machines can only transmit black and white files with limited resolution in a specific format such as the Tagged Image File Format (TIFF). Further, the transmission speed can be very slow compared to today's Internet based standards. Not surprisingly, the faxing technology in recent years has faced increasing competition from Internet Protocol (IP) network (e.g. Internet, LANs, WANs, intranets, extranets, etc.) based alternatives (generally referred to as Internet faxing). For example, instead of standalone fax machines, fax servers may be utilized in enterprise network environments. Typically, a fax server is a server computer having the necessary fax software and hardware to receive and send faxes over IP networks. Using fax servers may reduce the cost of transmission since there is no telephone connection charge when sending a fax over the Internet.

Internet based alternatives to physical fax machines are not without drawbacks. One challenge is that the Internet carries a vast range of information resources and services over a hodge-podge of protocols. For example, a user may send an email over the Internet, upload a file to a network site, and make a phone call over the Internet. The email may be sent via the Simple Mail transfer Protocol (SMTP), the file may be uploaded via the File Transfer Protocol (FTP), and the phone call may be conducted using the Voice over Internet Protocol (VoIP). Many existing network protocols do not meet the secure, traceable and non-repudiable needs of today's businesses. For example, the email (along with any attachment) as well as the file sent over the Internet unencrypted can be vulnerable to interception.

Additionally, network faxing solutions may include the need to access fax modems, routers or the PSTN (e.g. telephone lines) at the user's physical location. Increasingly, however, in most other areas of communication, including telephony itself, the trend has been toward use of the IP network based protocols (e.g. SMTP, FTP, VoIP, etc.). Accordingly, many traditional fax users no longer wish to maintain telephone lines or other access to the PSTN. It would therefore be desirable to give these users the ability to continue sending and receiving faxes without having to maintain local access to the PSTN.

SUMMARY

To address these needs, among others, embodiments of systems and methods for the sending, delivery and receiving of faxes are disclosed herein. In particular, certain embodiments include a fax connector that may be deployed at a user's site, and a faxing system that may be deployed remotely from the user's site. The fax connector can be accessed at the user's site over a computer based network in order to perform functions associated with faxing, including sending, receiving and obtaining status on faxes. The fax connector deployed at the user's site communicates with the remotely deployed faxing system to send, receive, obtain status on, or perform other functions associated with, faxing.

Because, in most cases, fax users already perform faxing utilizing fax servers, fax appliances, fax software, etc. connected to an computer based network (e.g. an IP (or other protocol) based network), faxing can be accomplished using embodiments of such systems and methods substantially without deviation from the user's previous faxing methodologies or workflows. Thus, such users can use their familiar fax environment without the restrictions of using a browser and without the need to maintain local telephony hardware, licenses, or telephone lines.

In certain embodiments, a set of services deployed on a cloud computing platform may be configured to receive a request over a computer based network to send a fax from a fax connector at a user's site, receive the document and destination telephone number associated with the fax and send the fax over the PSTN using a fax service.

In one embodiment, the fax service may send a request to the set of services to determine if there any faxes to send. The set of services may receive the request, determine that the fax is to be sent and return the document to the fax service over the computer based network.

One or more embodiments may receive a request for a status of the fax from the fax connector and return the status to the fax connector over the computer based network. The status may be updated by the fax service over the computer based network.

In other embodiments, the fax service may receive a fax over the PSTN, and send the document associated with the received fax to the set of services which determines a fax connector identifier to associate with the received document and sends the document to the fax connector at the user's site associated with the fax connector identifier over the computer based network.

These, and other, aspects of the invention will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings. The following description, while indicating various embodiments of the invention and numerous specific details thereof, is given by way of illustration and not of limitation.

Additionally, the functions of the disclosed embodiments may be implemented on one computer or shared/distributed among two or more computers in or across a network. Communications between computers implementing embodiments can be accomplished using any electronic, optical, radio frequency signals, or other suitable methods and tools of communication in compliance with known network protocols. It will be understood for purposes of this disclosure that a service is one or more computer processes, computing devices or both, configured to perform one or more functions. A service may present one or more interfaces which can be utilized to access these functions. Such interfaces include APIs, interfaces presented for a web services, remote procedure calls, remote method invocation, etc.

Before discussing specific embodiments a brief overview of the context of the disclosure may be helpful. As discussed above it is desirable to give these users the ability to continue sending and receiving faxes without having to maintain local access to the PSTN.

To that end, attention is now directed toward the embodiments of systems and methods for the sending, delivery and receiving of faxes disclosed herein. In particular, certain embodiments include a fax connector that may be deployed at a user's site, and a faxing system that may be deployed remotely from the user's site. The fax connector can be accessed at the user's site over a computer based network in order to perform functions associated with faxing, including sending, receiving and obtaining status on faxes. The fax connector deployed at the user's site communicates with the remotely deployed faxing system to send, receive, obtain status on, or perform other functions associated with, faxing.

Because, in most cases, fax users already perform faxing utilizing fax servers, fax appliances, fax software, etc. connected to an computer based network (e.g. an IP (or other protocol) based network), faxing can be accomplished using embodiments of such systems and methods substantially without deviation from the user's previous faxing methodologies or workflows. Thus, such users can use their familiar fax environment without the restrictions of using a browser and without the need to maintain local telephony hardware, licenses, or telephone lines.

Turning now to FIG. 1, one embodiment of an architecture of just such a faxing system is depicted. Fax architecture 100 includes a fax connector 106, fax intermediary system 130 and fax sender/receiver (s/r) system 140 communicating over a computer based network 170 which may be, for example, the Internet, an internet, an intranet, a LAN a WAN, an IP based network, etc. Fax intermediary system 130 has access to a data store 136. Fax s/r system 140 includes one or interface to PSTN 120 and is configured to send or receive faxes over the PSTN 120.

Fax connectors 106 are installed at a site where users wish to send faxes. Users 102 in such an architecture 100 may be companies, individual users, or any other entity wishing to send or receive faxes. Accordingly, fax connector 106 may be one or more computing devices or one or more computer processes executing on one or more computer devices utilized by such users 102 to send or receive faxes. Fax connector 106 provides an interface such as an API or hardware interface through which a fax to send may be received from a client 104 of the fax connector 106. These clients 104 may include a fax machine, a printer, an enterprise resource planning (ERP) system, etc. The fax connector 106 may communicate with fax intermediary system 130 over network 110 to send such a receive fax or to receive faxes.

Fax intermediary system 130 may be one or more computing devices comprising a fax connector facing service 132 and a fax s/r facing service 134. The fax connector facing service 132 may be configured to receive a fax; store the fax in data store 136; report on a status of a previously received fax to be sent; determine if there are any faxes associated with a requestor in the data store 136; obtain faxes from the data store 136; and return one or more of these faxes to a requestor. Thus, fax connector facing service 132 may present an interface through which a request to send a fax may be received along with the document and phone number associated with that fax; an interface through which a request to check the status of a fax may be received and a status returned to the requestor; and an interface by which a request to determine if there are any faxes associated with a requestor may be received and one or more faxes associated with that requestor returned.

Fax s/r facing service 134 may be configured to determine a fax to send from data store 136; obtain and return a fax from the data store 136; receive a status on a sent fax; update the status of a sent fax in data store 136; receive a fax; and store a received fax in the data store 136. Accordingly, fax service 134 may present an interface through which a request to determine if there are any faxes to send may be received and one or more faxes returned; an interface through which a request to update the status on a fax may be received along with data identifying the fax and the status on the fax; and an interface through which a received fax can be received including the document and one or more phone numbers associated with the received fax.

Fax s/r facing service 134 may communicate with fax s/r system 140 over network 110 to send or receive a fax. Fax s/r system 140 includes fax s/r service 142. Fax s/r service 142 is configured to request a fax to send at a certain time interval and send any faxes received in response to this request over the PSTN 120; update the status of a sent fax; receive a fax over the PSTN 120; and upload a received fax.

Accordingly, when a user 102 in architecture 100 wishes to send a fax he may utilize a client 104 at the user's site to send the fax. Client 104 provides the fax to the fax connector 106 through the interface provided by the fax connector 106. Fax connector 106 then sends a request to fax connector facing service 132 to send the fax. Fax connector facing service 132 stores the fax received from the fax connector 106 in the data store 136. At some point, fax s/r service 142 sends a request to fax s/r facing service 134 to determine if there are any faxes to send. Fax s/r facing service 134 may receive the request, determine that there is a fax stored in the data store 136 to be sent and return this fax to the fax s/r service 142. Fax s/r service 142 may receive this fax and send the fax to its destination over the PSTN 120.

During the sending of the fax, or thereafter, the fax s/r service 142 may send a status of the fax to fax s/r facing service 134. Fax s/r facing service 134 may then update the status of the fax in the data store 136. At some point, then, the fax connector 106 may send a request to the fax connector facing service 132 inquiring as to the status of the fax. Fax connector facing service 132 may obtain the status of the fax from the data store 136 and return it to the fax connector 106, which may present it to a user at the user's site.

Similarly, a fax may be received at fax send/receive service 142 over PSTN 120. When such a fax is received, fax s/r service 142 may send the fax to the fax s/r facing service 134. Fax s/r facing service 134 may determine the fax connector 106 associated with the fax and store the fax in the data store 136. At some point, then, the associated fax connector 106 may send a request to the fax connector facing service 132 to determine if there are any faxes associated with the fax connector 106. Fax connector facing service 132 may obtain the associated fax from the data store 136 and return the fax to the fax connector 106 which may then present the received fax to a user through the interface provided by the fax connector 106.

While it should be understood from a review of the above description that embodiments as disclosed may be implemented using a wide variety of architectures and hardware or software systems; that a fax intermediary system and a fax s/r system may be one or multiple systems that may or may not be distributed; that all of the services presented may or may not be one or multiple services with one or more interfaces; and that these one or more services may be implemented and accessed in a variety of manners, it will be useful here to describe a particular embodiment in more detail.

As discussed above, in some cases it is desirable to remove telephony from a user's site. However, embodiments of the systems and methods disclosed herein may have many users. Thus, entities implementing or administering embodiments of the systems and methods presented herein may be responsible for multiple phone lines associated with multiple users. As phone lines require a relatively large amount of infrastructure it may be desirable to centralize management of the telephone lines associated with these users. As the users themselves may be geographically distributed it is also desirable to maximize such user's access to the fax intermediary system to reduce downtime and allow substantially simultaneous access from multiple users to the fax intermediary system.

Therefore, in one embodiment, an entity implementing embodiments of the systems and method disclosed herein may implement the fax s/r system at a location over which they maintain control while the fax intermediary system may be implemented in a cloud based computing environment. By maintaining control of the access to the PSTN at a central location under the control of the entity, user's security concerns about access to the PSTN may be assuaged.

The service or services of the fax intermediary system may, however, be deployed using a cloud based service provider, such as Microsoft Windows Azure, Amazon EC2, vMware vCloud, Google's cloud, etc. By deploying the services of the fax intermediary system in the cloud, such services can utilize the storage and functionality provided by the cloud provider while achieving increased accessibility and reliability and simultaneously alleviating the entity providing embodiments of such faxing systems and methods from the need to maintain the hardware or connectivity necessary for the provisioning of such services.

With that in mind, turning now to FIG. 2, one embodiment of an architecture of a faxing system where certain services are deployed in a cloud based computing environment are depicted. Fax architecture 200 includes a network 270 over which a fax connector 206, fax sender/receiver (s/r) system 240 and a set of fax services deployed in a cloud based computing environment may communicate.

Fax connector 206 is provided at a site where users wish to send and receive faxes and may have an associated identifier (i.e. the fax connector identifier). One or more telephone numbers associated with a user's fax line are configured such that any calls to those numbers are received over PSTN 220 at phone lines coupled to fax s/r system 240. Thus, providers of embodiments as depicted herein may notify or otherwise arrange with telephony providers, to configure one or more telephone numbers associated with the user employing fax connector 206 such that calls to these numbers received at telephone lines of PSTN coupled to fax s/r system 240.

Fax connector 206 provides an interface 202 through which a client of the fax connector 206 may send faxes, receive faxes, check the status on sent faxes, etc. Fax connector 206 comprises three services: send fax service 204, status service 205 and receive service 208. Send fax service 204 may be configured to receive a document and a phone number from the interface, convert the document to a particular format (e.g. TIFF) if desired, send a request that the fax be sent and receive an identifier for that fax in return. Status service 205 may be configured to send a request for status on a sent fax along with a fax identifier, receive the status of the fax in return and present this status to a user through interface 202. Receive service 208 may be configured to send a request to identify any faxes received for the user along with the fax connector identifier for the fax identifier 206 and receive one or more faxes returned in response to this request.

Cloud 240 may be a cloud based computing platform such as Microsoft Windows Azure Platform or the like. The set of faxing services deployed in the cloud include a connector facing send 232, connector facing receive 234, a fax service facing receive 236 and a fax service facing send 238. These services may have one or more interfaces that may be accessed over network 270 using hypertext transfer protocol (http) calls or other types of network protocols or interfaces.

The cloud 240 may also provide certain services that may be utilized by the deployed set of faxing services, such services may include, for example the Microsoft Windows Azure Storage services such as table storage 252, queue storage 254 or other forms of storage not depicted such as blob storage, etc. This storage may be used during operation of the set of service and may store various configuration information associated with the services. For example, queue storage 254 may be used to store entries associated with faxes to send, where each entry in the queue is associated with a job identifier for that fax while table storage 252 may be used to store a mapping table, a send fax table and a received fax table.

The mapping table may associate phone numbers with fax connector identifiers. Thus, for example, if a user's telephone number has been configured such that calls to this number is received at telephone lines of PSTN 220 coupled to fax s/r system 240 there may be an entry in the mapping table associating this phone number with the fax connector identifier for that user's fax connector 206. The send fax table may associate job identifiers associated with entries in the queue with various data associated with a corresponding fax, including the document of the fax, the telephone number where the fax is to be sent, a fax connector identifier associated with the fax, a status associated with the fax, or other information. The received fax table may also be stored in the table storage 252, where the received fax table may include the document of the received fax, a fax connector identifier associated with fax connector where the fax is to be sent, the telephone number from which the fax was received, or other information. Other services provided by the cloud 240 (not depicted) may also be utilized (e.g. in the case of Microsoft Windows Azure Platform: Web Role, Worker Role, VM Role, Access Control, Content Delivery Network, Caching, etc. Other services in other cloud based computing platforms may also be utilized).

The connector facing send 232 may have an interface for sending faxes through which a request to send a fax may be received. Such a request may include the document to be faxed (which may be in TIFF format or another electronic format) and a phone number where the fax is to be sent. When such a request is received, the connector facing send 232 may enqueue that fax in queue storage 254, store data associated with the fax in the table storage 252 and return an identifier of the fax (i.e. a fax identifier) to the fax connector 206. Connector facing send 232 may additionally have an interface through which a status inquiry may be received along with a fax identifier. In response, connector facing send 232 may access the table storage 252 to read a status of the fax corresponding to the fax identifier from the table storage 252 and return the status of the fax to the requestor.

Connector facing receive 234 may have an interface through which a request for received faxes may be received along with a fax connector identifier. In response, the connector facing receive 234 may access table storage 252 to determine if there are any received faxes associated with the fax connector identifier. One or more of these faxes may be returned to the requestor by connector facing receive 234.

Fax service facing send 238 may have an interface through which a request for faxes to send may be received. In response, the fax service facing send 238 may access queue storage 254 to determine if there are any faxes waiting to be sent and select one or more of these faxes based on a priority. As will be noted queue storage 254 may be a type of queue (e.g. Microsoft Messaging Queue (MSMQ), IBM MQSeries, etc.) that allows priority to be implemented in conjunction with the queue. Thus, entries in the queue associated with faxes may be selected based on almost any priority desired, for example, timing, quality of service, source or destination, or some other criteria. When a fax has been selected, the fax identifier may be used to access the fax in the table storage 252 and the fax returned to the requestor.

The fax service facing send 238 may also have an interface through which a request to update the status of the fax may be received along with a status and a fax identifier. The fax service facing send 238 may then update the status of the fax in the table store 252.

Fax service facing receive 236 may have an interface through which a request to upload a received fax may be received, along with the document and telephone number from which the fax was received. When such a request is received, the fax service facing receive 236 may access the table storage 252 to determine a fax connector identifier associated with the phone number from which the fax was received and store the fax in association with the fax connector identifier in the table storage 252.

Fax service 242 is configured to request a fax to send at a certain time intervals, receive a fax identifier, a document, and an associated telephone number in response and send the received fax to the telephone number over the PSTN 220. During the sending of the fax the fax service 242 can send a request to update the status of the fax along with the fax identifier and an updated status. Such a request may be sent one or more times while the fax service is sending the fax over the PSTN 220 (e.g. a request may be sent after each page is sent, after the entire fax is completed, etc.). Fax service 242 may also receive faxes over PSTN 220. When a fax is received the fax service 242 may send a request to upload the fax along with the document and the telephone number from which that fax was received.

As can be seen then, the fax connector, fax s/r system and the set of fax services deployed in the cloud may interact to send, deliver and receive faxes. Embodiments of this process may be illustrated in more detail with reference to FIGS. 3A1-3B. Referring first to FIG. 3A1-3A3, one embodiment of a method for the sending of a fax employing an architecture including cloud based fax services is depicted. Initially at step 302 a user wishing to send a fax may provide a document and an associated phone number as a destination for the document. The document may be received by the send service of the fax connector at the user's site and, at step 304, may be converted (e.g. to a Tagged Image File Format (TIFF) or another format) by the send fax service of the fax connector at the user's site. Alternatively, the document may not be converted, or may be converted at another location. The send fax service of the user's fax connector can then send a request to the connector facing send service deployed in the cloud at step 306 requesting that a fax be sent. The request may include the document and the destination phone number (or these may be sent subsequently).

When this send request is received by the connector facing send service in the cloud at step 308, the connector facing send service may enqueue a job in queue storage for the sending of the fax associated with the received send request at step 310. When the job is enqueued, the queue storage in the cloud may return a job identifier associated with the created entry in queue storage. This job identifier is utilized by the connector facing send service to create an entry in table storage at step 314, where the entry associates the job identifier for the fax with the document and phone number provided in the request. The connector facing send service can then reply to the send service of the fax connector with the job identifier at step 316. The send service of fax connector may receive and store this job identifier at step 318 such that it may be utilized in subsequent processing, such as for example, a subsequent status inquiry.

At some point then, at step 319 the fax service may send a request to the fax service facing send service to determine if there are any faxes to be sent. Fax service facing send service may receive this request at step 320, access the queue storage to determine if there are any job entries in the queue storage and determine one or more of these jobs at step 322. As discussed above, this determination may be based on a priority associated with entries in the queue storage.

If there is a job to be sent, the job identifier of the determined entry may be determined from the entry in the queue. This job identifier may be utilized to access the entry in the table storage associated with that job identifier and the document and phone number associated with the job identifier read from the table at step 324 and returned to the fax service at step 326. In some cases the job identifier may also be sent to the fax service to be utilized for subsequent processing, for example, status updates and the like.

The fax service may receive the fax at step 328 and send the fax to the phone number over the PSTN at step 330. During the sending of the fax over the PSTN the fax service may send one or more requests to the fax service facing send service to update the status of the fax during or after sending of the fax over the PSTN. This request may include a job identifier of the fax and a status (such as transmitted, failed, o.k., etc.) or an associated time. The fax service can also update a reporting service at step 334, such that data on sent faxes may be accessed or otherwise processed.

Fax service facing send service may receive the status update request at step 336 and update the entry in the table storage associated with the job identifier with the received statues at step 338.

At some point then, status service of the user's fax connector may send a status query request to the connector facing send service at step 340. This request may contain a previously provided job identifier as discussed above. The connector facing send service may receive the status inquiry request at step 342, access the table storage to determine the job status at step 344 and return the job status at step 346. The status service of the fax connector can then receive and display the job status to the user at step 348.

Moving now to FIG. 3B, one embodiment of a method for the reception of a fax employing an architecture including cloud based fax services is depicted. As discussed above, the PSTN is configured such that calls on one or more phone numbers associated with a particular fax connector are received at the fax service. Similarly, then, a table may exist in the table storage of the cloud based fax service that has entries mapping these phone numbers to the fax connector identifier associated with that fax connector.

Initially, then, at step 352, the fax service may receive a fax associated from a phone number over the PSTN. The fax service may then send a request to upload a received fax to the fax service facing receive service at step 354. This request may include the document received along with the phone number from which it was received and the phone number of the fax's intended destination (or the document and phone number may be sent at a subsequent time). The fax service can also update a reporting service at step 356, such that data on received faxes may be accessed or otherwise processed.

The fax service facing receive may receive the request to upload the fax at step 358. At step 360 the fax service facing receive service may then access the table mapping phone numbers to fax connector identifiers to determine the fax connector identifier associated with the destination phone number. The fax is then stored in an entry in table storage in association with the associated fax connector identifier at step 362. Other information may also be associated with the entry, including, for example, the time received, the phone number from which it was sent, the destination phone number, etc. If, a associated fax connector identifier cannot be found, the fax may be stored in a dead letter table, and the reporting data updated.

At some point, then, at step 364 the receive service of the fax connector may send a request to the connector facing receive service. This request may identify the fax connector using the fax connector identifier for that fax connector. When this request is received at the connector facing receive service at step 366, the connector facing receive service determines at step 368 if there are any faxes associated with that fax connector identifier of the request by accessing the table storage to determine if there are any entries in the received fax table associated with that fax connector identifier. If any entries are found in the table storage one or more of the faxes may be returned to the receive service at step 370. The determination of which of the faxes to return may be based on almost any criteria desired, such as time received or the like. Additionally, multiple faxes may returned in response to a received request. More specifically, the connector facing receive service may access an entry associated with the fax connector identifier to obtain the document and telephone number to which the fax was sent or from which the fax was received. This document along with one or more of the phone numbers may be returned to the receive service of the fax connector.

When the receive service of the fax connector receives the fax at step 372, it may display the received fax at step 374 through its interface. This may entail displaying the fax through a computer display, printing the fax on a client device or some other method of display entirely.

As can be seen then, using embodiments of the systems and methods disclosed herein a user can use their familiar fax environment without the restrictions of using a browser and without the need to maintain local hardware, licenses, or telephone lines. However, the user can see status updates associated with outbound faxes in their local system as they would using conventional techniques. Additionally, received faxes may come into the user's local system leveraging the rules and workflows to which they are accustomed.
